BENCH-PLAN E.

SPECIFICATION forming part of Letters Patent No. 453,524, dated J une 2, 1891.

Application filed August '7, 1888. Serial No. 282,165. l(No model.)

.To all whom. it 77u03/ concern.-

Be it known that I, SAVERTO TUO'rI, of the city, county, and State of New York,have invented a new and Improved Bench-Plane, of which the following is a full, clear, and eX- act description.

My invention relates to bench-planes for wood-workers use, and has for its object to provide asinlple, easy-working, efficient, and durable plane of this character.

The invention consists in certain novel features of construction and combinations of parts of the plane, all as hereinafter dcscribed and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure l is a vertical longitudinal section of my improved bench-plane, taken on the line in Fig. 2. Fig. 2 is a plan View of the plane partly broken away and in section. Fig. 3 is a bottom face view of the plane partly broken away. Fig. a is a vertical transverse section of the plane, taken on the line y y in Fig. l. Fig. 5 is a cross-section taken on the line .zzz in Fig. l. Fig. 6 is atop perspective view of the plane iron or cutter, and Fig. 7 is a detail perspective View of the nut and part of the screw by which the cutter is adjusted endwise.

The plane-stock A is made with the usual top recess a, which opens to a throat or passage a', up through which escape the shavings made by the cutter B, which rests on or at the inclined bottom face or wall of the recess.

In the plane-stock and at the lower inclined wall of the recess a there is formed a groove or recess to accommodate a screw C, which is fitted at its forward end in a metal step-bearing c, set into the stock, and at its rear part is reduced in diameter at two places c c2, which form journals which are fitted, respectively, to a split box or bearing I) and a block E. The two halves or parts of the bearingl) are screwed or otherwise fixed to the plane-stock, and the block E is also a nut, into which is fitted a transversely-ranging screw F, which is journaled to or in the plane-stock and cannot move endwise, and has a head or nger-piece f, which is accommodated in a recess made in the side of the plane-stock and does not project beyond the stock, and thus does not interfere with the free working of the plane.

The nut E is provided with an upper luge, which fits laterally within the slot b of the plane iron or bit Il, and the nut is laterally slotted at c', where the main adj Listing-screw C passes through it, and whereby as the screw F is turned the nut E maybe caused to move laterally either way in the plane-stock, and the nut-lug e will shift the back end of the planeiron laterally to adj ust the cuttingedge of the iron properly with relation to the workingface of the plane either before or after the iron has been adjusted endwisc by the main screw C, working in a nut G, litted on it, and as presently explained. It will be noticed that the bearing and nut D E, by fitting the reduced parts of the screw C, prevent endwise motion of the screw.

The nut G is preferably formed with pendent end lugs o g', into which the screw O is fitted, and at its upper face the nut is provided with a series of transverse notches g, into which one or more transverse bars b, which cross the plane-iron slot b, are adapted to enter when the plane-iron is adjusted in the stock.

The wedge II is provided at its lower face with a plate I, which is fixed to the wedge at one end and at its other or free end is adapted to bear on a cross-bar b of the plane-iron or on the adjusting-nut or on both the cross-bar and nut, and onto which the plate I, which is preferably elastic, may be forced by a screw J, fitted into the wedge and preferably into a metal nut j, set into it. The forward end or part of the wedge enters beneath a cross bar or rod K, xed in the stock across its recess a, and the bar forms a fulcrum on which the wedge will` rock when the screw .I is tightened to cause its extreme front end 71. to clamp the planc-iron down hard to the planestock very near the cutting-edge of the iron, and thus Vfirmly -hold it to prevent chattering of it when the plane is in use and assuring smooth clean work. The effect in this respect would be the same were the plate I dispensed with, in whichcase the screw J would bear directly on the plane-iron or on its adjustingnut; but the plate I is preferably used, as it IOC for adjusting the piane-iron endwise for a finer or coarser cut, and which may be done without loosening the wedge-clampingscrew.4

lVhen the plane iron or cutter lwears so it cannot be set farther ahead by operating the screw, the cross-bar Z9 of the iron may be set into another front notclrg after/the nut is run back on the screw, this adjustment allowing all the tempered forward part of the iron to be used.

The plane-stock has the usual back and front handles A A2, andis also provided with a working-face oi' peculiar construction, the front part of which face is made adjust-able backward or forward to narrow or broaden the shaving-throat a of the plane-stock, and as will next be described.

The larger section or portion M of the plane` face and its smaller adjustable section or portion Nare made on the same general principle, or with a metai frame having strips of hard wood inserted in longitudinal grooves thereof. The face-section M is made with a cast-metal frame O, which has abroad cross-bar 0 behind the shaving-throat a of the plane-stock and beveled at the upperface to give substantial support to the plane-iron and to preventundue Wear of that part of the plane-face just behind the cutting-edge of the iron or at the back of the shaving-throat of the plane-stock, which usually wears quickly when made wholly or partly of wood. From each side of the cross-bar o there projectsa forward extension o of the metal frame O, which form forward side parts m m of the main face-section M. These parts o o give support to the front sliding section N of the plane-face, as presently described, and atv their front ends and above the section N they are connected and braced bya flangepiece or bar m', which is screwed to the frontend ofthe plane-stock andv really forms the front cross-bar or part of a flange 02, which projects upward all around the frame O and above its solid top plate o3 far enough to receive screws o, which pass through the flange to hold the frame O and its front extensions o 0,or,y in other words, the entire main plane-face section M m m, securely to the plane-stock.

Behind the metal cross-bar 0 and within the margin of the frame O said frame is provided with a series of longitudinally-ranging thin metal ribs or plates o5, which are cast on the back plate 03 of the frame and are set apart to provide spaces or form grooves between them, and into which are tightly fitted a series of hard-wood strips P, and the forward extensions 0 0 of the frame O are also made hollow to accommodate like strips P, as most clearly shown in Figs. 3, 4, and 5 of the drawings.

The plane-face section N consists of a metal frame R, the inner face-plate fr of which is provided with side tongues r r', which enter grooves made in the opposite front side eX- tensions m m of the main plane-face section M. On the plate r and between end lips or flanges r2 r2 of the frame R there is cast a series of lips or plates r3, set apart to provide between them a series of grooves or spaces, into which are tightly fitted a series of hard-wood strips S, like tion M. t Y

In the forward end of the plane-stock and above its facesection N is provided a transverse slot orgroove t, which accommodates a nut-block T, fitted to threads of a screw U, which is j ournaled in the plane-stock and traverses the recess t, and is providedat one end with a finger-piece or head u, which works in a recess at the side of the stock, so as to be out of the way in working the plane. The ends of the lower part of the nut T are inclined the same way horizontally, and are preferably rounded a little, so as to enter a diagonally-ranging slot V, which is formed at the inner face of the adjustable plane-face section N and preferably in the back of the metal frame R of said section. It is obvious that as the screw U is turned in one direction the nut T will slide in the plane-stock recess t, which guides it laterally, and also in the diagonal recess V of the movable plane-face section N, and will slide said section forward to open the throat dfarther or make Yit broader, and that by turning the screw U in the'other direction the face-section N will be, moved backward nearer to the cutting-edge of the plane-iron to narrow the shaving-throat a of the plane, as the nature of the work to be done may require. A

It will be seen that the plane-iron B sets at quite a sharp angle with the working-face of the plane. Consequently it will cutveryeasily, and this feature, combined with the simple and efcient means provided for adjusting the plane-iron endwise and laterally, as hereinbefore explained, and the adjustability of the face-section N to regulate the size of the shaving-throat a', insures true and smooth working of the planeon any quality or grade of lumber, whether it be soft or hard.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is-L 1. The combination, with the plane-stock and its bit, of the longitudinally-extending screw having a bevelgear'on its outer end, a

those P of the other face-sec- ITO IZO
